12.4.4.9 LinearCS

element name=LinearCS type=gml:LinearCSType substitutionGroup=gml:AbstractCoordinateSystem complexType name=LinearCSType complexContent extension base=gml:AbstractCoordinateSystemType complexContent complexType gml:LinearCS is a one-dimensional coordinate system that consists of the points that lie on the single axis described. The associated coordinate is the distance — with or without offset — from the specified datum to the point along the axis. A LinearCS shall have one gml:axis property element. EXAMPLE Usage of the line feature representing a pipeline to describe points on or along that pipeline. NOTE gml:LinearCS can only be used for simple continuous linear systems. Linear Reference Systems LRS, particularly as applied to the transportation industry, are specified in ISO 19133 and are not implemented by this International Standard.

element name=UserDefinedCS type=gml:UserDefinedCSType substitutionGroup=gml:AbstractCoordinateSystem complexType name=UserDefinedCSType complexContent extension base=gml:AbstractCoordinateSystemType complexContent complexType gml:UserDefinedCS is a two- or three-dimensional coordinate system that consists of any combination of coordinate axes not covered by any other coordinate system type. A UserDefinedCS shall have two or three gml:axis property elements; the number of property elements shall equal the dimension of the CS.
